Introducing the future of bicycle light technology- Ai Alert. Combining Artificial Intelligence with our advanced ALERT rear taillights to bring you the most accurate cycling brake light on the market. The light automatically detects brake events and intelligently changes output mode to Active Alert - a rapid 250-lumen flash “brake light” mode; signaling deceleration, effectively communicating your actions to traffic and fellow cyclists, enhancing rider visibility and safety. *Ai Alert lights come pre-programmed and do not collect rider data.

The Saddle Ai Alert 250 Rear is a premium, highly visible saddle-mounted rear taillight combined with advanced Ai Alert technology. Equipped with 10 super-bright LEDs providing a beam pattern optimal for light dispersion in even the most challenging conditions. The fully CNC-machined aluminum construction with wide angle optics for 270° of visibility, offers 7 combined solid and flash output modes- from the eye-catching max 250 lumens emitted in both Active Alert and Day Flash modes to the impressive 60 hours of runtime in FEMTO mode. Rigorously tested to IPX7 Waterproofing standards to ensure functionality in the toughest weather conditions. The Saddle Ai Alert 250 Rear features an 1100 mAh battery capacity. Simply unscrew the light from the saddle-mounted body to easily detach for quick and easy USB-C charging accessibility (cable not included).

Nice Comforter, Thin Sheets
Color: Blue, Size: Queen, Color: Blue, Size: Queen
I bought this comforter set for my guest bedroom, and the price was great. It’s really pretty and fits the bed perfectly. It includes a comforter, a sheet set with pillowcases, and two pillow shams. It arrived vacuum-sealed, when I opened it, I was impressed by how soft it felt—just right for a comforter. It seems like it will be warm yet cooling at the same time, and I love its thickness. The only downside was the sheet set. While the comforter is fluffy and cozy, the sheets felt cheap—very thin—and I prefer them thicker. They’re labeled 100% polyester but are just too thin for my taste. If you’re not picky about sheets, this set would be perfect. They are soft, just not thick enough. Overall, I really like the comforter, but I’ll use my own sheets because of the thinness of the included ones. I would have given it five, but the sheets bring it down to four.

Beautiful Sage Green Set That is Super Soft and Cozy!
Color: Sage Green, Size: Queen
​I am absolutely in love with this sage green bedding set. The queen comforter has a gorgeous pre washed crinkled texture that gives the whole bedroom a really cozy, aesthetic look without needing to be ironed. It is incredibly fluffy and has just the right amount of weight to it, making it perfect to use all year round. The brushed sheets that come with the bed in a bag are surprisingly soft against the skin, and everything fit my queen mattress perfectly right out of the box. ​The color is a beautiful, calming sage green that matches my room decor perfectly. I have already washed the sheets and comforter once, and they held up great in the machine without losing their softness or shrinking.

Soft All-in-One Queen Bedding Set With Lightweight Comforter
Color: Beige, Size: Queen
This 7-piece queen bedding set is a solid all-in-one option for anyone looking to refresh a bedroom with a clean, aesthetic look without spending much. The comforter has a lightweight feel with a soft crinkled texture that gives it a relaxed, lived-in appearance while still looking modern and put together on the bed. The included sheets and pillowcases are soft and smooth against the skin, with enough comfort for year-round use. The comforter itself is light but still provides enough warmth for most seasons, making it practical for both warmer and cooler months. Fit is generally accurate for standard queen mattresses, and the set comes complete with everything needed, which makes setup simple and convenient. The overall look is cohesive, with a soft beige tone that blends easily into most room styles. While it is not a luxury heavyweight bedding set, it offers good comfort, style, and value for the price, making it a strong choice for guest rooms, first apartments, or an easy bedroom upgrade.

Standard Comforter. Thin Scratchy Sheets
Color: Dark Green, Size: Queen
This is an ok set for the price. I’m mostly using the comforter for a guest room. It’s a light-medium thickness. The color and size are true to description. The sheets that come with the set are very thin and not as soft as the comforter.
